I'll be heading to germany in early august. I'll be arriving in FRA in the afternoon, probably jet lagged. A full day the next day and then ICE down to Munich the following morning. Then two full days and then flying out.

I plan to get a SIM card for my phone as soon as I arrive so I can get data to help me get around in town. Any tips on where to buy?

Also, I've noticed that eventhough U stations show up on google maps, I can't get it to route on U routes. It will select much longer S routes which are alot longer. Is there an alternate app I can use for navigating around town?

Any tips on must-see attractions? I hear there is more to see in Munich than FRA.
